pyjaspar 2.1.1

A serverless interface to Biopython to access different versions of JASPAR database

pyJASPAR

A Pythonic interface to JASPAR transcription factor motifs

pyJASPAR uses Biopython and SQLite3 to provide a serverless interface to JASPAR database to query and access TF motif profiles across various releases of JASPAR.

pyJASPAR provides access to the following releases of JASPAR database:

• JASPAR2022

• JASPAR2020

• JASPAR2018

• JASPAR2016

• JASPAR2014

Note: This is a serverless SQLite wrapper around the Biopython JASPAR module Bio.motifs.jaspar.db which requires JASPAR MySQL database sever connection details.

If you have git installed, use this:

git clone https://github.com/asntech/pyjaspar.git
cd pyjaspar
python setup.py sdist install

How to use pyJASPAR?

Once you have installed pyjaspar, you can create jaspardb class object:

>>> from pyjaspar import jaspardb

#Create the JASPAR2020 release object
>>> jdb_obj = jaspardb(release='JASPAR2020')

#Fetch motif by ID
>>> motif = jdb_obj.fetch_motif_by_id('MA0095.2')
>>> print(motif.name)
YY1

#Fetch motifs by TF name
>>> motifs = jdb_obj.fetch_motifs_by_name('CTCF')
>>> print(len(motifs))
2

#Get CORE vertebrates collection
>>> motifs = jdb_obj.fetch_motifs(
    collection = 'CORE',
    tax_group = ['vertebrates']
    )
>>> print(len(motifs))
746
## loop through the motifs list and perform analysis
>>> for motif in motifs:
        pass

Note: Above methods return Bio.motifs.jaspar.Motif object. You can find more details here

Find available releases

>>> print(jdb_obj.get_releases())
['JASPAR2022','JASPAR2020', 'JASPAR2018', 'JASPAR2016', 'JASPAR2014']
